Hi all,

I'm actually working one a water-air compression using a liquid piston. I'm using Fluent and the VOF method.

I would like my mesh to be refined in the interface region which has a known thickness (10 cells approximatively). This could be done with the mesh adaptive method, but the problem here is that my region is time-dependant. Indeed, the interface is moving accordingly to the known velocity U(t). So I know the interface position at each time step.

Can anyone help me with my problem ? Is there any implemented solution in Fluent that is doing this ? Feel free to ask more precisions if needed.

This is also my first cfd-online topic, so please excuse me for any wrong things I've done so far,

Thank you for your help,

Pierre
